WATCH-WINDING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 296,170, dated April 1, 1884.

Application filed January 2, 1883.

My invention relates to a watch in which two mainspring-drums having cog-circles meshing with a pinion in a spur-wheel are 1o employed.

The object of my inventionis to so construct the winding department that the watch can be wound back and to the right hand, the det'acement of the dial-plate being thus prevented;

15 to-locate all the winding and driving mechanism between the cap-plate, top plate, and the pillar-plate, so as to reduce the thickness of such a watch; to simplify the construction by making a single ratchet-wheel on the wind- 20 ing-arbor do duty for both mainsprings by beingv engaged by a single ratchet-pawl; to enable the watch to run longer; to provide a device capable of adaptation to stem-winding mechanism andk to any escapement.

My improvement consists in the construction described hereinafter, and pointed out in the claim.

In order that my invention may be fully understood, I will proceed to describe it with 3o reference to the accompanying drawings, in

which- Figure l is a rear view of a watch-movement embodying my invention. Fig. 2 is a similar view, from which portions of the hous- 3 5 ing-plate have been removed to expose the details of my winding mecl'ianism. section on the lines x x.

A is the front and B the rear plate of a watch-movement.

C is a shield or cap to protect and journal Fig. 3 is a the two springs pivots d d and the winding-- arbor G, and formed with recesses e, e, andf. I employ two mainspring-drums, D D', containing, respectively, two similar mainsprings, which, being of the customary construction, are not shown in the drawings. The shafts d d of said springs have two precisely similar spur-wheels, E E', occupying the recesses e e', said spur-wheels both gearing into 5o an intermediate wheel, F, occupying recess j" of the cap, and upon the winding-arbor G.

(No model.)

I The arbor G extends through the rear or pillar plate in the manner shown. A ratchetpawl, L, engages a ratchet-wheel, M, on the arbor G. A spring, N, keeps the ratchetpawl L in engagement with the ratchet-wheel. Each drum has a spur-wheel, as shown at H and H', in the same plane, so as to engage the nearly opposite sides of the intermediate pinion, I, mounted on whose shaft is a spurwheel, J. that gears into thehour-hand pinion K. By this means I provide within the compass ot' an ordinary watch-movement and between the customary housing-plates two mainwound by asingle customary right-hand winding-arbor, both act on the train, and are capable of continuing it in motion for a week or other protracted period, depending on the aggregate strength of the springs. position of an additional speed-wheel and pinion at least doubles the number of rotathe spring-barrel, this of course imposing a greater labor on the spring, which is overcome by doubling the spring-power.

Having thus described my invention, the following is what I claim as new therein and desirel to secure by Letters Patent: l

In a watch, the combination of front plate, A, rear plate, B, shield or cap C, formed with recesses e ef, two mainsprings7 drums, D D', having spur-wheels H H in the same plane, intermediate pinion, I, with which the drum spur-wheels engage, spur-wheel J on the intermediate pinion-shaft, vhour-hand pinion engaged by the spur-wheel J, mainsprings7 shafts d d,journaled in the cap, spur-wheels EE on the springs7 shafts, occupying the recesses e c, winding-arbor G, extending through the rear plate and cap, spur-wheel F on the arbor, occupying the recess f and meshing with the springs spur-wheels E E, a ratchet-wheel, M, on lthe arbor, and a spring ratchet-pawl to engage the ratchet, as set forth.

In testimony of which invention I hereunto set my hand. l f
